Weekly Degree Day and DOE Storage Number Comparison Tables

Weekly Degree Day Comparison TablesUpdated 7/6/2017 AM

The above charts compare the weekly total gas weighted degree days for last week, this week, and next week to the 11 weeksduring the past 5 years that had the most similar gas weighted degree day totals. If a federal holiday occurred during a givenweek, it is marked as "Yes", otherwise as "No". Two averages of the gas weighted degree days and EIA storage numbers arepresented. One that averages all 11 of the closest matches, and one that only averages weeks that did not have a holiday.

NOTE: these EIA average values should not be used as a direct forecast, but just as a weather-based estimate. Theaverage EIA values are just averages of similar weeks, and no attempt is made to adjust for supply/demand differences,or other factors.

Green colors denote above average degree day totals Red colors denote below average degree day totals

May - Sept 2017 US Population Weighted CDD Anomaly Plume (vs 30 Year Avg)








61% of years warmer than Normal, 39% of years cooler than Normal when projecting end of season total using using observations to date plus weather from past years

Updated 7/6/2017 AM

Below are long-range NG storage projections based on the latest Frontier Weather 15 day and seasonal forecast. Theprojections are based on a regression of weekly degree day totals to weekly storage numbers. No price/storage levelproduction response is built in, so future projections are based on unchanging supply and non-weather relateddemand trends. Circled areas on graphs denote observed or forecast values at those points in time.

Source file locations for data in various degree day tables in report

The HR in the file name designates that it is derived from our new higher resolution population weighted data set.

http://www.frontierweather.com/degreedays/HR_FW_USPopulationWeightedData.csvhttp://www.frontierweather.com/degreedays/USPopWeightedbyYearDDs.txthttp://www.frontierweather.com/degreedays/HR_FW_1996_Forecast_NG_Elec_Combo_HDDs.csvCombination of number 1 for CDDs and number 3 for HDDs.http://www.frontierweather.com/degreedays/USGasWeightedbyYearDDs.txthttp://www.frontierweather.com/degreedays/HR_FW_1996_Forecast_FuelOil_Propane_HDDs.csvhttp://www.frontierweather.com/degreedays/HR_FW_1996_Forecast_FuelOil_Propane_HDDs_byPadd.csvhttp://www.frontierweather.com/degreedays/HR_FW_CensusRegionPopulationWeightedData_alt.csv

The FW in the file named disignates that population/gas weights for all years of data are fixed to 2010 values. A set of files with the same name, but without the "_FW" in the file name is also available, and in those files the weights vary by year. The fixed weights are used in this report to allow for better comparison to values from previous years since differences in values are only due to differences in weather and not differences in population patterns as well.

The main difference between the new data files used in this report and the old data files used in the previous version of the report is that the U.S. and regional degree day totals are derived from 230 cities in the new data files versus 120 cities in the old files. This difference is more apparent on the regional level than the national level.
